Improved brick-machine



UNITED STATES PATENT OFFICE.

WILLIAM H. PAIGE, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR TO HIMSELF AND ELISHA CHILD, JR., OF SAME PLAGE.

IMPPtOVED BRICK-MACHINE.

Specification forming part of Letters Patent No. 45,377, dated December 6, 1864.

To all whom it may concern Beit known that I, WILLIAM II. PAIGE, of Springiield, county of Hampden, State of Massachusetts, have invented a new and Improved Machine for Making Bricks 5 and I do hereby declare that the following is a full and exact description thereof, reference beinghad to the accompanying' drawings, and to the letters of reference marked thereon.

Bricks are ordinarily made of two kinds, one known as common77 and the other presseth and as these are often made atf the same manufactory it will be seen that a i machine which will make both kinds with slight alteration is a great improvement on all before invented. This I claim as one of the features of my invention, besides simplif vi ng the general arrangement ofthe machine, so as to greatly economize in the cost.

My machine may be described as follows:

In the drawings, Figure l is an end view; Fig. 2, a side elevation. Fig. I represents the machine having the front ot' the box IV re moved.

In front of the ordinary box or hopper A, in which the clay is ground, I place a countershaft, G, run by the bevel-gear a b, which operates by means of the eccentrics Bti() a double press, D E 5 also, on the same shaft the grooved cam F, which operates by means ot' the connection c andthe arms l L l, the

shafts (l d having the camsj'jVfHf/l and the ratchet g 71 operated by the same cam by means of the connection 7s, connecting the two levers l l.

I will now describe the method of making pressed brick. These are merely common brick subjected to heavy pressure in a mold which contines the clay, and are thus made Inuch more compact than the common. The clay is placed in the hopper A, as usual, and

'ground to the proper consistency. It now runs through the opening O into the box NV and under the presses D E. These are now operated by the eccentrics B O, andthe clay is rst pressed into the openings n n by the press D, and then the press E, having the pieces s s attached to it, continues the pressl ure, when the clay is confined in the molds K, except atthe upper edges of the openings n n, which are beveled to allow the superduous clay to escape. At the same time the movable bed, having on it the molds K, is brought up by means ofthe camsffff on the shafts d d against the bottoni of the box W, thus confining the clay in this direction. When the clay is pressed, the bed falls, at the 4 saine time the ratcheth is operated on bythe l pawl g, and turns the roll P. As this is done, a new mold, similar to K, is placed on the hand It and carried forward. As the roll turns, the mold K, containing the brick, is pushed out at the front, and the brick are taken to the kiln; the mold K is taken to the rear end ofthe machine to be run through again.

The operation ot' making common brick is generally the same, except that the pins p p are removed from the arms l l l, leaving them free to turn ou the shafts d d', so that l the movable bed S is not operated, but rests on the pieces T TT, inserted for the purpose; also, the press E is removed and the opening in the pressD iled so that the clay is simply pressed through the holes n n and into the mold K, which is run through as before. As this runs out, the scraper X strikes the top of the brick and makes them ofa uniform thickness.

fhatI claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the box W', having suitable openings in its bottom, with the bed S, presses D and E, operated by the eccentrics B and O, or their equivalents, substani tially as described.

2. The combination of the cam F, armsl* l, connections O and K, pawl g, ratchet h, rolls P Pf, and hand R, when used in the manner and for the purpose described.

3. The combination of the cam F, connection c, levers lll, shafts dd', calnsffff, and bed S, when used for the purpose described.
